UPDATE 02/04/18: The orchestral version of Penumbra received it's premiere with the Butler County Symphony Orchestra, led by Matthew Kraemer, on Saturday, February 3, 2018.  The orchestra played beautifully and Tom killed it!  Orchestra and audience alike were effusive in their praise of the work and Tom's performance!

The project now moves into its next phase. Stephen is working on the band transcription, to be premiered later this year.  We have some other very cool news to share, and will do so once all of the details are finalized.

The commissioning consortium remains open for new members to join while the band phase of the project is in progress.

We've had new members joining in the days leading up to the premiere, and we think once people hear this piece, they will want to join as well.  

See all of the current members and JOIN the consortium below.  A huge shout out and THANK YOU to all of our members!

Penumbra will be published by Adam Frey /

Euphoniumist Tom Mavovsky of the U.S. Air Force Band of the Golden West has commissioned composer Stephen Barr to write a new work: a single-movement, concerto-style work for euphonium and symphonic ensemble.  Tom has requested a slow to medium tempo piece in a lyrical style, approximately 8-10 minutes in length. Two versions will be written: one for euphonium and orchestra, and one for euphonium and wind ensemble.  A reduction for euphonium and piano will also be prepared.

The premiere is scheduled for February 3, 2018 by the Butler County Symphony Orchestra, and Fall 2018 by the Slippery Rock University Wind Ensemble.  Copies of the score and parts will be mailed to the consortium members after the completion of the premiere and any necessary edits are made; after which all contributing members will have first rights to regional premiere performances.

As leaders of the consortium, the Butler County Symphony Orchestra and the SRU Wind Ensemble will have the exclusive right for a year to make the first professional recordings.
